Maverick Office Supplies review for Kindly: Payment Reminder Pro

I've used this app only for a few days, but I can tell you it's paid for itself 30x already. This makes it easy to auto send past due reminders to encourage buyers to pay their invoice. The staff is great and fast at responding to questions, and helping set up the DNS settings. Like I said, this app is a no brainer if your business issues invoices.
